Gel: Is that his "final" story? The one that they decided to be their final scenario. For Arkham, was the word virgin actually used? it could also reference how Arkham dabbled in black magic. What exactly is the contextaround angry Trish? I mean, its not too far off that an angry woman who looks like your mom reminds you of your angry mom. Its not so much that people ignore this information, its that its hard to prove and relies a lot on taking someones word. There is again context, considering art-books are full of what could have but never made it. For all I know that is a section of the book is for scrapped stories or scenerios

Jay: Yamato existed for 2000 years or more before Vergil. Rebellion is different because it has no mention of existing before Dante and is stated to be explicitly linked to Dante and his power.

We have also seen swords in the series be thrown like boomerangs so that theory doesn't quite hold. Sanctus also called it to himself.

Dante and Vergil both need Devil arms to sustain Devil Trigger. Dante recieved his DT when near death and he drew power from the nearby Rebellion. Sanctus was able to resonate with Sparda Sword. My theory is that Nero's DT activated as a response to his will to live, but needed an energy source and resonated with Yamato to make that happen
